Technology for driving comfort
and safety
Vehicle equipment
In this chapter, all production, country, and
optional equipment that is offered in the model
range is described. Equipment is also described
that is not available because of, for example,
selected options or coun try version. This also
applies to safety relate d functions and systems.
Park Distance Control
PDC
The concept
PDC assists you with parking in reverse. Acoustic
signals and a visual indi cator warn you of the
presence of an object behind the vehicle. To
measure the distance, there are four ultrasonic
sensors in either bumper.
These sensors have a range of approx. 6.5 ft/
2m. However, an acoust ic warning does not
sound until an object is approx. 24 in/60 cm
from the rear corner sensors, or approx. 5 ft/
1.50 m from the rear center sensors.
PDC is a parking aid that can indicate
objects when they are approached slowly,
as is usually the case when parking. Avoid
approaching an object at high speed; otherwise,
physical circumstances ma y lead to the system
warning being issued too late. <
Automatic mode
With the engine running or the ignition switched
on, the system is activated automatically after
approx. 1 second when you engage reverse
gear or move the automatic transmission selec-
tor lever to position R. Wait this short period
before driving.
Acoustic signals
As the distance between vehicle and object
decreases, the intervals between the tones
become shorter. If the distance to the nearest
object falls to below roughly 1 ft/30 cm, then a
continuous tone sounds.
If the distance remains co nstant, e.g. when driv-
ing parallel to a wall, the acoustic signal stops
after approx. 3 seconds.
Malfunction
Indicator lamp lights up. PDC has failed.
A message appears on the Control
Display. Have the system checked.
To avoid this problem, keep the sensors clean
and free of ice or snow in order to ensure that
they will continue to operate effectively. When
using a high-pressure cleaner, do not direct the
jet toward the sensors for lengthy periods and
only spray from a distance of at least 4 in/10 cm.
PDC with visual warning
To have the system show distances to objects on
the Control Display. The contours of distant
objects are shown on the Control Display even
before the acoustic sign al sounds. The display
appears on the Control Display as soon as the
transmission is shifted into reverse or the
selector lever is moved into the R position.
System limitations
Even with PDC, final responsibility for esti-
mating the distance between the vehicle
and any obstructions always remains with the
driver. Sensors, too, have blind spots in which
objects cannot be dete cted. Moreover, ultra-
sonic detection can reach its physical limits with
objects such as trailer tow bars and couplings,
thin and wedge-shaped objects, etc. Low
objects already indicated, such as curbs, may

Automatic transmission
Before driving into the car wash, make sure that
the vehicle can roll:
1.Place the remote control, even with Comfort
Access, in the ignition lock.
2. Move the selector lever to position N.
3. Release the parking brake.
4. Switch off the engine.
5. Insert the remote control in the ignition lock
so that the vehicle can roll.
Steam jets/high-pressure washers
When using steam jets or high-pressure
washers, make sure that you maintain
sufficient distance from the vehicle and do not
exceed a maximum temperature of 140 7/
60 6 .
If the distance is too close, the pressure too high,
or the temperature too high, parts of the vehicle
can be damaged, or water can penetrate.
Observe the operating instructions for high-
pressure washers. <
Do not spray sensors, such as the Park Dis-
tance Control, with high-pressure washers
for a long time or at a distance of less than 1 ft/
30 cm. <
Manual washing
Use a great deal of water and, if necessary, car
shampoo when washing your car by hand. Clean
the vehicle with a sponge or a washing brush
applying a slight amount of pressure.
Before cleaning the windshield, deacti-
vate the rain sensor or turn off the ignition
to prevent unintentional wiping. <
Observe local regulations regarding wash-
ing vehicles by hand. <
Headlamps
Do not wipe dry and do not use abrasive or
corrosive cleaning agen ts. Remove dirt and
contamination, such as in sects, by soaking with
shampoo and then washing with plenty of
water.
Do not remove accumulated ice and snow with
an ice scraper; use window deicers instead.
Windows
Clean the outside and inside of the windows and
mirrors with a window cleaner.
Do not clean the mirrors with cleaners
containing quartz. <
Wiper blades
Clean with soapy water and change regularly to
prevent the formation of streaks.
Wax, preservatives and dirt on the win-
dows cause streaks wh en the windshield
wipers are on, and can cause premature wear
of the wiper blades and interfere with the rain
sensor. <
Care of the convertible top
The appearance and service life of the convert-
ible top largely depends on its proper care and
operation.
Please follow these instructions:
>Never attempt to fold and stow the convert-
ible top in the convertible compartment
when the top is wet or frozen. Otherwise,
water stains, mildew, and chafe marks may
occur.
> If water spots occur on the inside headliner
despite precautions, remove them using a
microfiber cloth and interior cleaner.
> If the vehicle is parked in an enclosed area
for a longer period of time, make sure that
there is sufficient ventilation.
> Remove any bird droppings immediately,
since they have corrosive properties which
will corrode the conver tible top and damage
the rubber seals.
